• When the machine runs outside, always use a protection switch (30 mA max.) against fault current.
• Pull the plug out of the socket and make sure is switched off when the machine is not under supervision, e.g. in case of putting up and stripping down, in case of voltage drop or when fixing or mounting an accessory.
• Switch the machine off if it stops for whatever reason. This way you avoid that it starts suddenly and not under supervision.
• Do not use the machine when one part of the housing is damaged or in case of damages on the switch, cable or plug.
• Pay attention that the speed indicated on the tool meets or is higher than the max. speed indicated on the machine.
• Check the accessories before use; do not use damaged products.
• Before use, make sure that the tool is correctly fixed and fastened. Let it run idle for about 30 seconds in a safe position. If considerable vibrations occur or if other defects are recognised, switch off immediately.
• While working, lead the line cord / extension cord and the extraction hose to the back away from the machine.
• Power tools have to be inspected by a specialist in regular intervals.
• Never carry the machine at its cable.

Assembly

Before initial use, assemble the extraction hood and the base plate.

Extraction hood

• Position the extraction hood so that the suction nozzle (A) is located just to the right of the operating handle (see fig.).
• Secure the extraction hood using the three supplied M 5×25 screws and 5.3 mm washers (B) on the mounting on the gear housing.
• Between gearbox and exhaust hood, the intermediate ring (see picture below) are mounted.

Base plate

• Push the base plate onto the spindle (C) of the machine and secure using the supplied M6x20 screw.
• For assembly, use the supplied screwdriver

Electrical Connection

• First, check the correspondence between voltage and frequency against the data mentioned on the identification plate. Voltage differences from + 6% to – 10% are allowed.
• The EWS 400 is made in protection class II. Only use extension cables with a sufficient cross-section. A cross-section which is too small might cause a considerable drop in performance and an overheating of machine and cable.

Recommended minimum cross sections and maximum cable lengths

Switching on and off

Before connecting the machine to the mains supply, make sure that the machine is switched off.
Short-Time Operation
Switching-on: press on/off switch
Switching-off: release on/off switch
Permanent Operation
Switching-on: press the on/off switch and, keeping it pressed, engage the arrestor button
Switching-off: press the on/off switch and let it go off again

Attention

In case of every stop of the machine or a power cut, the lock button has to be released immediately by pressing the on/off switch. Consequently, you can avoid an unintentional restart of the machine (physical hazard). The machine is equipped with an electronic switch. With this switch the speed can be regulated according to the pressure on the button. Only use the electronic switch when you want to start the machine slowly. Permanent use with reduced speed can cause an overload because the motor then gets less cooling air and therefore the machine will be overheated much faster.

Tool Change

Attention!

• Before the beginning of all works disconnect the plug from the mains!
• Only use original accessories in order to allow an optimal extraction.
• Press the sanding paper in a way on the sanding plate that the extraction holes are not covered.
• The 4 hole punch of both discs makes it possible to centre exactly and to position the sanding paper on the machine easily.

Attention!

• Before you start working, check whether the accessory has the exact position.
• Let the machine start running in a safe position for a short time. In case the machine does not run easily, immediately stop working.

Dust Extraction

• Dust which appears during work is harmful to health. For this reason, use an industrial vacuum cleaner while sanding.
• The appropriate Wet/Dry Vacuum Cleaner DSS 25 M is available as accessory. Directly connect it to the nozzles which are meant for it on the dust hood.

Handling
Connect the lead cable of the dry-wall sander with the industrial vacuum cleaner and then connect the extraction hose with dust hood of the sander. Lead the extraction hose and the cable to the back away from the machine. Activate the switch-on automatic on the vacuum cleaner. Switch the machine on and put it carefully on the surface you want to work on. Hold the machine with both hands and move it in a linear or rotary way. For sanding works directly on wall edges you can remove a segment from the protection hood. This allows working even on spots which are usually hard to reach.

Attention!
Do not touch rotating parts!

Care and Maintenance

• Before the beginning of the maintenance or repair works you have to disconnect the plug from the mains.

Repairs may be executed only by appropriately qualified and experienced personnel. After every repair the machine has to be inspected by an electric specialist. Due to its design, the machine needs a minimum of care and maintenance. However, the following points have to be observed:

• Always keep the power tool and the ventilation slots clean.
• During work, please pay attention that no particles get inside the machine.
• In case of failure, a repair has to be carried out by an authorised service workshop.
• Our after-sales service responds to your questions concerning maintenance and repair of your product as well as spare parts.
• EIBENSTOCK’s application service team will gladly answer questions concerning our products and their accessories.

Environmental Protection

Raw Material Recycling instead of Waste Disposal

In order to avoid damages on transportation, the tool has to be delivered in solid packaging. Packaging as well as unit and accessories are made of recyclable materials and can be disposed accordingly. The tool’s plastics components are marked according to their material, which makes it possible to remove environmental friendly and differentiated because of available collection facilities.

Only for EU countries
Do not dispose of electric tools together with household waste material! In observance of European Directive 2012/19/EU on waste electrical and electronic equipment and its implementation in accordance with national law, electric tools that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

Noise Emission

• Measured sound values determined according to EN 62841-2-4.
• Typically the A-weighted noise levels of the product are:
• Sound pressure level LpA 88 dB(A)
• Sound power level LwA 77 dB(A)
• Uncertainty K 3 dB

Wear ear protectors

• Vibration total values ah and uncertainty K determined according to
• EN 60745:
• Vibration emission value ah 1,0 m/s2
• Uncertainty K 0,1 m/s2

The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Warranty

According to the general supply conditions for business dealings, suppliers have to provide to companies a warranty period of 12 months for redhibitory defects. (To be documented by invoice or delivery note.) Damage due to natural wear, overstressing or improper handling are excluded from this warranty. Damages due to material defects or production faults shall be eliminated free of charge by either repair or replacement. Complaints will be accepted only if the tool was returned in non-dismantled condition to the manufacturer or an authorized service centre.
